Circuit Design Suite (Multisim, Ultiboard)

[645645645]

Hi,

I really need you help. I've bought a book with a Multisim 10.1 Student Edition.

When I want to simulate something, I receive the following error message:

"This circuit has no power sources: unable to determine the simulation timestep automatically.
Please add a power source or set the simulation timestep under "Interactive Simulation Settings" to proceed."

I am using Windows XP.

Some time before I downloaded Evaluation Version from NI website and had the same problem.

Thank you for your help.

Best,

Anis

Hey guys, Lacy and Devon_H,
I was facing the same problem each time I tried running my circuit. And every time I get this error : "This circuit has no power sources: unable to determine the simulation timestep automatically."
So I need to know if you fixed up thiss issue or if I need to reinstall the program.
note I've tried my circuit on my freind's Pc and it seems to functoin normally
I'll attach the circuit and the error msg
